Description
Technical field
The present invention relates to nano-packaging field of material technology, more particularly to a kind of nano-PVC packing material and its system
Preparation Method.
Background technology
Nanometer new packing material prescription is one and in space, is directly sorted by change naturally former within 100 nanometers
The project of the new nano-packaging material that son is created out with molecule.Nanometer new packing material and the field be modern strength and
The starting point of modern technologies innovation, the discovery of new rule and principle are founded with brand-new theory and give basic science, there is provided new
Chance, this can become the new power of important reform in many fields.Nanometer new packing material prescription is tiny due to SAIZU, gathers around
There are many peculiar performances.Baibich in 1988 etc. has found that magnetoresistive ratio reaches for the first time in nanometer Fe/Cr MS
50 percent, compare with general ME and want a big rank, and be negative value, respectively to the same, referred to as GMR.Afterwards also
Huge ME is found in nanometer system, tunnel knot and Perovskite structures, membrana granulosa.The inside Perovskite structures are one or nine
Be within 9 years to find and with very big ME, be called CMR, find in tunnel knot for TMR.
Nanometer film is divided into membrana granulosa and dense film.Membrana granulosa is that nano particle sticks together, centre have it is extremely tiny between
The film of gap.Dense film refers to that film layer is fine and close but crystallite dimension is nano level film.Can be used for：Gas catalysis（Such as vehicle exhaust
Process）Packing material；Filter packing material；High density magnetic recording packing material；Photosensor package material；Plane shows
Show device packing material；Superconduction packing material etc..
Nanometer technology need not be put as a kind of emerging science and technology of most market application potential, its potential importance
Doubt, some developed countries all put into substantial amounts of fund and carry out research work.As colonial has set up research in nanotechnology center, Japan
Portion of culture and education section is classified as nanometer technology as one of four big primary study exploration projects of packing material science.In Germany, with hamburger
University and Mainz university are nanotechnology research center, and government provides funds the research of 65,000,000 dollars of support micro-systems every year.
The country, many scientific research institutions, institution of higher learning also organize scientific research strength, carry out the research work of nanometer technology, and achieve certain
Achievement in research, it is main as follows：
The synthesis of directional nano array carbon nanotube, is completed by Inst. of Physics, CAS Xie Sishen researcher etc..They utilize
Chemical gas-phase method efficiently prepares about 20 nanometers of aperture, the CNT that about 100 microns of length.And thus prepare nanotubes battle array
Row, up to 3 millimeters × 3 millimeters, between CNT, spacing is 100 microns to its area.
But, compared with the advanced technology of developed countries, we also have very big gap.The German Ministry of Science and Technology was once
Jing made prediction to nanometer technology future market potential：They think that nano structure device market capacity is up to 2000
637500000000 dollars, nano-powder, nano composite ceramic and other nano combined packing material market capacitys are up to 5457
Hundred million dollars, nanofabrication technique market capacity is up to 44,200,000,000 dollars, and the assessment technique market capacity of nano-packaging material will
Reach 27.2 hundred million dollars.And the breach of prediction markets may be in information, communication, environment and medicine and other fields.
In a word, nanometer technology is just becoming scientific and technological circle of various countries focus of interest, foretold as Academician Qian Xuesen that
Sample：" the characteristics of structure below ran and nanometer will be next stage development in science and technology, can be a technological revolution, so as to
To be the Industrial Revolution again of 21 century."
On October 19th, 2011, EU Committee passed through the definition to nano-packaging material, again this definition was carried out afterwards
Explain.According to the definition of EU Committee, nano-packaging material is a kind of powdery being made up of basic granules or lumps
Natural or hand-filling material, one or more three-dimensional dimensions of this basic granules between 1 nanometer to 100 nanometers, and
And the total quantity of this basic granules accounts for more than 50% in all total number of particles of whole packing material.
1 nanometer is equal to part per billion meter.On nanoscale, some packing materials have many specific functions.Receive
Rice packing material is used widely in the work and life of people.
The application study such as nanometer technology fundamental research and new packing developing material is obtained for quickly development, and
And be widely used in industries such as Traditional Packing material, medical equipment, electronic equipment, coating.In industrialized development
Aspect, except nano-powder packing material is in addition to a few countries such as the U.S., Japan, China tentatively realize large-scale production,
Nano biological packing material, nano electron device packing material, nanodoc diagnosis packing material etc. product still in
Develop the stage.Up to 22.3 hundred million dollars, annual growth is 14.8% to global nanometer new packing material market scale in 2010.
A few years from now on, with the increasing that various countries are put into nanometer technology application study, nanometer new packing will be big with materials industrialization process
Big to accelerate, market scale will have and high-volume increase.Nano titanium oxide, nano zine oxide in nano-powder packing material, receive
Several products such as rice silica have formed certain market scale；The extensive nano ceramics packing material of application of nanopowder,
The packing materials such as nano-textile packing material, nanocomposite coatings are also succeeded in developing, and tentatively realize industry metaplasia
Produce, nano-powder particle is just stepping up from experimental research achievements to product industry in the application of medical diagnosis preparation, microelectronic
Change production mode reform transfer.
